Sanjo refers to the playing of a solo instrument to the accompaniment of a janggo (hourglass-shaped drum), moving from a slow to a fast rhythm, in four to six movements. Daegeum Sanjo is an instrumental folk music played solo on the daegeum (bamboo flute).
Daegeum Sanjo is said to have been created by Park Jong-gi in the early 20th Century. Its musical features are embellishments designed to add rhythm and tempo to melodies, nongeum (embellishment sounds improvised by the performer), teul (forms), and extemporaneousness.
Daegeum Sanjo has been handed down with its unique features intact. A skilled performance based on arrangements that aim to make it easier to listen to has the power to render both tension and joyousness.
